Welcome to the UCL entry for iGEM 2012.

UCL iGEM proposes a synthetic biology approach for the bioremediation of micro-plastic pollutants within the marine environment, with emphasis on regions of excessive debris accumulation, such as the North Pacific ‘garbage patch’.

We intend to engineer enhanced adhesive properties in Escherichia Coli and marine bacteria Roseobacter Denitrifican and Oceanibulbus Indolifex, of the Roseobacter clade. To alter the composition and dynamics of resultant biofilms for the adhesion of micro-plastic pollutants, with an extended vision of creating mass aggregates, or ‘Plastic Islands’.

We will attempt to demonstrate micro-plastic particle aggregation and several additional genetic components, including plastic degradation, salinity/osmotic tolerance in E. Coli, bacterial buoyancy and novel active biological containment strategies, for an integrative approach to marine bioremediation.

After months of planning, we are now rallying to construct a ‘plastic island’ using the principles of synthetic biology. In so doing we hope to provide a solution to one of the world’s major environmental problems – the North Pacific Garbage Patch.

The North Pacific Garbage Patch is the largest of many garbage patches identified around the world. The waste from these patches enters the digestive systems of resident organisms, which are affected either by the physical size of the plastic, or its toxicity from adsorbing organic pollutants.

We saw the merits of using synthetic biology to overcome this problem, especially as conventional methods cannot target the majority of the waste - microplastics. By ‘synthesising’ a new strain of bacteria, capable of detecting, aggregating, and buoying these elusive microplastics, we aim to construct ‘Plastic Islands’ for
